Method Detail

toJSONObject

public static JSONObject toJSONObject(String string)
                               throws ParseException

Convert an HTTP header string into a JSONObject. It can be a request header or a response header. A request header will contain

 {
     Method: "POST" (for example),
     "Request-URI": "/" (for example),
     "HTTP-Version": "HTTP/1.1" (for example)
  }
 

A response header will contain

 {
     "HTTP-Version": "HTTP/1.1" (for example),
     "Status-Code": "200" (for example),
     "Reason-Phrase": "OK" (for example)
  }
 

In addition, the other parameters in the header will be captured, using the HTTP field names as JSON names, so that

     Date: Sun, 26 May 2002 18:06:04 GMT
     Cookie: Q=q2=PPEAsg--; B=677gi6ouf29bn&b=2&f=s
     Cache-Control: no-cache
 

become

 {...
     Date: "Sun, 26 May 2002 18:06:04 GMT",
     Cookie: "Q=q2=PPEAsg--; B=677gi6ouf29bn&b=2&f=s",
     "Cache-Control": "no-cache",
  ...}
 

It does no further checking or conversion. It does not parse dates. It does not do '%' transforms on URLs.

Parameters:

string - An HTTP header string.

Returns:

A JSONObject containing the elements and attributes of the XML string.

Throws:

ParseException

toString

     Method: "POST" (for example),
     "Request-URI": "/" (for example),
     "HTTP-Version": "HTTP/1.1" (for example)
  }
 

A response header must contain

 {
     "HTTP-Version": "HTTP/1.1" (for example),
     "Status-Code": "200" (for example),
     "Reason-Phrase": "OK" (for example)
  }
 

Any other members of the JSONObject will be output as HTTP fields. The result will end with two CRLF pairs.
